GUIDING DEVICE FOR WRAPPING-MACHINES.

To all whom it may concern."

Be it known that I, FRANK M; PIERCE, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain 'ings, and to the numerals of reference "marked thereon, which form a part of this specification my co-pending application. for double wrapper wrapping machines, filed No vember 26th, 1915, SerialNo. 63,502.

This invention relates to an automatic guiding or centralizing .means for articles such as annular objects, particularly coils of wire or tires, placed in a wrapping machine which are automatically adjustable for arti- Ito's an object therefore of this invention to provide a guiding and centralizing device automatically adjustable for articles of different size to maintain the same properly positioned in the wrapping machine during a wrapping operation.

It is furthermore an important object of this invention toconstruct a pivotally mounted counterweighted guiding and centralizing means for an article being wrapped in a wrapping-machine which is automaticallyadjustable for difierent articles and as ingmechanism for an article in a wrapping This invention constitutes a division of- Specification oi Letters- Patent. Patented Aug.. 9 191'? led: February machine serving effectually to maintain an article in proper position while revolved or otherwise advanced in the machine during the wrapping operation; The invention"(in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: v Figure 1 is a front'elevation of a wrapping machine equipped with a device enibodying the principles of myinvention.

F 1g. 2 1s a central vertical section taken through the machine, with parts shown in I elevation.

Flg. 3 1s a top plan View of the guiding device detached from the machine.

Fig. 4 is a detail section taken on line 4-i of Fig. 2, with parts omitted.

Fig. 5 is a fragmentary top planview of the device, with parts omitted.

F ig. 6 is a top plan view of the counterweight detached from the guiding mechanism.

Fig. 7 is a rear end view of the mechanism shown in Fig. 3, with the weight detached.

Fig. 8 is'a section taken on line 8-8 of Fig.

As shown in'the drawings The frame of the wrapping machine is denoted as a whole bv the reference numeral 1, and is providcduvith an arched cross member 2, at the upper end thereof. The frame '1, is provided with upright guide rods or posts 3, on which brackets 4, are shdably mounted for vertical adjustment, and journaled in said brackets are supporting and driving rollers 5, upon which an article 6, such as a tire, coil of wire, or other annular object, is placed and supported for wrap ping. The details of construction and operation of the mechanisms by which the tire or other object is su-pported'and adjusted,-

are not entered into further than the brief description in the foregoing.

Held rigidly in the upperportion of the frame of the machine is acrescent shaped or open gap frame 7, provided with a plurality of rollers 8, and journaled to rotate around said frame upon the rollers is an open g'ap shuttle 9: Rotationof-the shuttle 9. through the ,eye of the annular object 6, serves to apply a-wvrapper.upon the article, the strip of wrapping material being drawn from a supply reel; 10,- lnoi-inte(l.upon the For the purpose oi' 1-naintaining the ar-' tic-1e being wrapped properly centrahzed' through the eye of the shuttle and guiding the article as it is rotated byv the machine,

aguiding means is provided com rising three rollers .14, arrangedin angle relation with one another, as sliown in Figs. 1,- 7 and 8, journaled orpivotcd in a bracket 15, secured upon alever 16, by means ofa bolt 17, adapted to engage through an aperture 18, provided in said lever. Said lever 5 16, is pivotedat its rear end upon a rear-- war-dly extending bracket 19, bolted to' the arched cross member 2, of the wrapping machine frame,

lever, are upwardly extending plates 20,

which extendon each s'ide 0t thebracket 19',-

thereby guiding said lever 16, in its pivotal movement, and a pin or b'olt'21, is removably' secured between said upright plates 20, in any one of a number of registering apertures 22, to limit the downward movement or adjustment of said lever 16,.as desired. As clearly shown in Figs. 2 and '5, the upper surface of the rear end of said lever 16, is provided with a series of notches denoted by the reference numeral 23,- which are formed in a central longitudinal rib on the surface of said lever, and a weight 24, having upwardly directed wing extensions 25, is adapted to be suspended on said lever by means of a--pin 26, engaging through said wing extensions of the weight and seating in. one of the notches 23, or" the lever. Said; weight is provided with a forwardly directed projection or extension. 27, which bears upwardly beneath the under surface of said lever 16, to brace the weight in its attached position on saidlever.

In operation, the rollers 1i, rest upon the periphery of the article 6, being wrapped, and, due to the weight 24 attached on the lever on which said rollers, are mounted, the same are brought to bear with a predetermined pressureupon the peripheryof the object. 'Due to the angled relation of said rollers, they engage. not only on the extreme outer periphery of the object, but.

I also downwardly oneach side thereof, thus guiding and centralizing the object, particularly at the point at which the wrapper is applied thereto by the shuttle. The pressure with whichthe rollers are brought to 55 bear upon the article may be varied by shifting the weight 25, along on the pivoted lever 16. In order to limit the downward.

A centralizing and guiding device for -wrappingmachines comprising a pivoted lever, roller means on the end thereof to machine,"comprlsing an adjustably weight ed pivoted lever, and roller means mounted on the end thereof adapted to bear upon the article substantially at the point of appli cation of the wrapper by the machine.

4. Ina device of the class described, a pivotally. mounted bracket, a roller rotatably mounted thereon adapted tobear on the article being wrapped, rollers rotatablv mounted on the bracket angularlv directed with respect to the aforesaid roller to engage the article wrapped thercbetween, and adjustable means for varying the pressnrr of the rollers on the article wrapped.
